Draft The Observation_Information class provides information about a science observation. The Observation_Information class provides information about a science observation. This section contains the simpleTypes that provide more constraints than those at the base data type level. The simpleTypes defined here build on the base data types. This is another component of the common dictionary and therefore falls within the pds namespace. The mission_phase_name identifies a time period within the mission. The orbit_number attribute identifies the number of the orbital revolution of the spacecraft around a target body. This value is N/A for cruise images. The product_type identifies a group of data products within a collection that have some property in common, such as processing level, resolution, or instrument-specific setting. Release_number is the number of a scheduled release of JunoCam data from PDS. The first Juno data release is Release 1. The release_number for a given product is always the first release in which it appears, and does not change if the product is revised later. The spacecraft_clock_start_count attribute provides the value of the spacecraft clock at the actual start of image acquisition. There may be small inconsistencies with start_date_time due to varying correlation between UTC and the spacecraft clock. For purposes of data analysis the spacecraft clock value should be used. The format of this field is compatible with the NAIF Toolkit software where s = seconds converted from the clock's coarse counter and m = seconds converted from the clock's fine counter. The tdi_stages_count attribute provides the number of time delay and integration (TDI) stages used to increase the exposure time of a JunoCam observation.
